TLDR
Sequential search methods characterized by a dynamically changing number of features included or eliminated at each step, henceforth "floating" methods, are presented and are shown to give very good results and to be computationally more effective than the branch and bound method.

Semi-supervised SVM for individual tree crown species classification

TL;DR: A novel semi-supervised SVM classifier is presented, specifically developed for tree species classification at individual tree crown (ITC) level, which provides classification accuracies significantly higher than those obtained by the standard supervised SVM and by a state-of-the-art semi- supervisory SVM (S3VM).

Texture analysis of carotid artery atherosclerosis from three-dimensional ultrasound images.

TL;DR: Based on DBC, WRS, ACC, and AUC texture features derived from 3D carotid ultrasound were observed to be more sensitive in detecting statin-related changes incarotid atherosclerosis than VWV suggesting that texture classifiers can be used to detect changes inCarotid Atherosclerosis after therapy.

A survey of feature selection methods for Gaussian mixture models and hidden Markov models

TL;DR: A review of the literature on feature selection techniques specifically designed for Gaussian mixture models (GMMs) and hidden Markov models (HMMs), two common parametric latent variable models, concludes that further research into unsupervised feature selection methods for HMMs is required and that established methods for GMMs could be adapted to HMMs.

A Comparative Study of Gender and Age Classification in Speech Signals

TL;DR: It is proven that gender classification can be performed with an accuracy of 95\% approximately using speech signal either from both genders or male and female separately, and the accuracy for age classification is about 88%.

A hybrid model of fuzzy min–max and brain storm optimization for feature selection and data classification

TL;DR: Experimental results indicate that FMM-BSO is able to produce promising results as compared with those from the original FMM network and other state-of-the-art feature selection methods such as particle swarm optimization, genetic algorithm, and ant lion optimization.

A Branch and Bound Algorithm for Feature Subset Selection

TL;DR: In this paper, a branch and bound-based feature subset selection algorithm is proposed to select the best subset of m features from an n-feature set without exhaustive search, which is computationally computationally unfeasible.

A Direct Method of Nonparametric Measurement Selection

TL;DR: A direct method of measurement selection is proposed to determine the best subset of d measurements out of a set of D total measurements, using a nonparametric estimate of the probability of error given a finite design sample set.

On the effectiveness of receptors in recognition systems

TL;DR: Some of the theoretical problems encountered in trying to determine a more formal measure of the effectiveness of a set of tests are discussed; a measure which might be a practical substitute for the empirical evaluation.
